Hello, everybody
i’m currently making a scene that reached about 30kk polygons and i really don’t have the option to use instances in it to preserve memory, so i stumbled up the problem that when i hit render, blender tells me that i’m out of memory (i’m using the CPU render and have 32gb of ram) can anyone give me a good idea how to tackle such problem ?
30k polygons is very small.
Supply a demo blend file for review
What OS and computer spec etc
Any effects ? (particles, cloth, fluid etc)
Any high res textures etc
no, you have it wrong, its 30KK which is 30 000 000 polygons. i’m running on a core i7-5820k, 32gb ddr4 hyper furyX, gtx 970 4gb ram. The blend file is almost 4gb large, i don’t know if i can suply it. the heaviest model is a tree that is a mix of sculpting and box modeling, almost everything done by hand cause i was looking for a certain look and the whole tree ended up being about 18 million polygons. i must add that i’m kind of new to cycles, i’m used to rendering with VRay and usually i would just use VRay proxy for such things (it’s like linking in blender, but it makes the computer generate the geometry from the HDD instead of loading it in RAM) also i do have quite a lot of particles, dust, water drops, bubbles etc … but the main problem is that tree, which for some reason can’t render even on it’s own as my PC runs out of memory
so far i think i had overcome the problem simply using this https://www.blender.org/manual/render/workflows/command_line.html but if there are any other ideas, i would be happy to check them out
I’m sure you can reduce a lot of models to a less heavy polycount.
-
the tree maybe can be reduced by repotology and/or the use of a displacement map
-
things that are further away from the camera dont need to be as detailed as the ones very close
